Mast Cell Tumors: "...They tend to disappear only to return again."

I've gotten conflicting diagnosis consistently, meaning whether to perform surgery or not. So, trust your own decisions over all others' opinions. > They are usually circular, flat, and slightly raised masses found anywhere on the body. Some are very itchy. They are usually found after the ferret has scratched them and they become slightly ulcerated and bleeding, leading to a round sore that may have a crusty scab with hair matted over top. If the scab falls off, the lesion is red, may ooze a little and will have no hair.
